Hey folks,

I haven't used the instance-store builder before - or indeed any instance-store backed EC2.

Could someone enlighten me as to why we need an S3 bucket and x509 certs for this builder? Why not just store the AMI on EC2 like with EBS-backed images?

Cheers
Matt

Instance store don't use EBS at all. An EBS AMI references a EBS snapshot which is used to boot the instance. AMI's for instance store backed instances does instead store a image of the root disk in S3 (a bundle), this image is encrypted with your key for security reasons.

Hi Rickard, thanks for that.

I'm totally across what EBS is and does - I've just never used instance-store backed EC2 instances. I thought it seemed odd that the AMI would be stored on S3, rather than under the "AMIs" section of the dashboard like the EBS instances, and wondered why that is.

The should also be listed under AMIs, but the bundle is in S3. This is similar to EBS backed AMIs which have there underlying snapshot listed in EBS Snapshots.

Ahh that makes more sense. I'll have a play around creating one now.

Thanks Rickard
